Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 132,452,645, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 132,452,645 | |
| -1 | -132,452,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,452,645.
Example:
1 x 132,452,645 = 132,452,645
and
-1 x -132,452,645 = 132,452,645
Notice both answers equal 132,452,645
With that explanation out of the way, let's continue. Next, we take the number 132,452,645 and divide it by 2:
132,452,645 ÷ 2 = 66,226,322.5
If the quotient is a whole number, then 2 and 66,226,322.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 132,452,645 | |
| -1 | -132,452,645 |
Now, we try dividing 132,452,645 by 3:
132,452,645 ÷ 3 = 44,150,881.6667
If the quotient is a whole number, then 3 and 44,150,881.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 132,452,645 | |
| -1 | -132,452,645 |
Let's try dividing by 4:
132,452,645 ÷ 4 = 33,113,161.25
If the quotient is a whole number, then 4 and 33,113,161.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 132,452,645 | |
| -1 | 132,452,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 415 | 1,079 | 5,395 | 24,551 | 122,755 | 319,163 | 1,595,815 | 2,037,733 | 10,188,665 | 26,490,529 | 132,452,645 |
| -1 | -5 | -13 | -65 | -83 | -415 | -1,079 | -5,395 | -24,551 | -122,755 | -319,163 | -1,595,815 | -2,037,733 | -10,188,665 | -26,490,529 | -132,452,645 |
